1. Convert units:
* Weight to mass:
- 1 lb = 0.453592 kg
- 850 lb * 0.453592 kg/lb = 385.55 kg (approximately)
* Speed to meters per second:
- 1 mph = 0.44704 m/s
- 66 mph * 0.44704 m/s/mph = 29.53 m/s (approximately)
2. Kinetic Energy Formula:
Kinetic Energy (KE) = (1/2) * mass * velocity²
3. Calculate:
KE = (1/2) * 385.55 kg * (29.53 m/s)²
KE ≈ 167,658 joules
Therefore, the kinetic energy of the motorcycle is approximately 167,658 joules.
